错误
线程“main”中的异常java.lang.ClassCastException:java.io.RandomAccessFile无法强制转换为org.apache.pdfbox.io.RandomAccessRead
at aechaec.PDFManager.ToText(PDFManager.java:43)
在aechaec.AechAEC.main(AechAEC.java:25)
Java结果:1
是由安全权限引起的吗?因为我在Mac上使用Netbeans?
答案 0 :(得分:9)
周围有许多过时的例子,它们可能会也可能不会起作用。请替换此代码
file = new File(filePath);
parser = new PDFParser(new RandomAccessFile(file,"r"));
parser.parse();
cosDoc = parser.getDocument();
pdfStripper = new PDFTextStripper();
pdDoc = new PDDocument(cosDoc);
这段代码:
pdDoc = PDDocument.load(new File(filePath));
pdfStripper = new PDFTextStripper();
并更新到2.0的发布版本。
